I had the XP-15 in my system for 8 months (Daniel Hertz M-6, M-5s, M-7's) and just replaced it with the XP-25. As fantastic as the XP-15 was, the XP-25 is even better (it needs to be be at some $10k) Prior system was all Cello with STRAD GMS.
As I have 2 turntables (TTW Momentus V2 Cu9999 and Goldmund Studio/T3F) and three cartridges (new Ortofon, Kiseki PurpleHeart Sapphire and van den Hul EMT-1) the front panel selectors for 2 inputs and multiple impedences) are quite useful.
As good as the old (over 20y) cartridges are, I am leaning to the new Ortofon Cadenza Black for regular listening, as it sounds more natural overall (no high frequency bump.)
